Figure 7

Effects of Scp on the mitochondrial biogenesis and adaptions. (a, b) ATPase activity, the activity of Na⁺K⁺ATPase and Ca²⁺Mg²⁺ATPase in muscle (a) and heart (b). (c) mtDNA content. (d) mRNA expression levels regarding mitochondrial biogenesis and adaption in skeletal muscle. (e) mRNA expression levels regarding mitochondrial biogenesis and adaption in the heart. (f) PGC1α and TFAM Western blotting bands in the skeletal muscle and heart. (g) relative protein expression levels of PGC1α and TFAM in skeletal muscle. (h) Relative protein expression levels of PGC1α TFAM in heart. Con: the control group; L-Scp: Scp low-dose group; M-Scp: Scp moderate-dose group; H-Scp: Scp high-dose group. All data are presented as (). The means marked with superscript letters are significantly different relative to others.
